OBJECTIVES This report details the National Center for Health Statistics' (NCHS) development of the 2006 NCHS Urban-Rural Classification Scheme for Counties and provides some examples of how the scheme can be used to describe differences in health measures by urbanization level. METHODS The 2006 NCHS urban-rural classification scheme classifies all U.S. counties and county-equivalents into si...

In a photolithographic system, the mask patterns are imaged through a set of lenses on a resist-coated wafer. The image of mask patterns physically can be viewed as the interference of the plane waves of the diffraction spectrum captured by the lens set incident on the wafer plane at a spectrum of angles. Two-beam interference fringe is the simplest format of the image. Consequently, two-beam i...

Gametes of Chlamydomonas reinhardi become activated for cell fusion as the consequence of sexual adhesion between membranes of mating-type plus and minus flagella. By using tannic acid plus en bloc uranyl acetate staining, and by fixing at very early stages in the mating reaction, we have demonstrated the following. (a) Activation of the minus mating structure entails major modifications in the...

Future global astrometry missions have targeted the determination of positions, parallaxes, and annual proper motions to the 10 mas level. This can be achieved through the use of fringe imaging interferometers, possibly featuring wide fields of view (e.g., Fizeau configurations). The basic location information is to be extracted from the fringe pattern by proper implementation of the detection ...

Despite its vital function in a highly dynamic environment, baleen is typically assumed to be a static material. Its biomechanical and material properties have not previously been explored. Thus I tested sections of baleen from bowhead whales, Balaena mysticetus, and humpback whales, Megaptera novaeangliae, alone or in groups representing miniature 'racks', in a flow tank through which water an...

AIMS AND OBJECTIVES To redefine the practice of rural nurses and describe a model that conceptualises the capabilities and characteristics required in the rural environment. BACKGROUND The way in which the practice of rural nurses has been conceptualised is problematic. Definitions of rural nursing have been identified primarily through the functional context of rural health service delivery....

This brief describes Medicaid’s role for 52 million nonelderly children and adults living in the most rural areas in the United States and discusses how expansions or reductions in Medicaid could affect rural areas. It shows:  Rural populations face significant challenges to their health care coverage and access. People who live in the most rural counties of America are spread across almost 2,...

The involvement of metacognition in mindfulness is already acknowledged in recent mindfulness models. The focus of the current paper is on how mindfulness may be seen to involve a particular subcategory of metacognitive feeling referred to as fringe consciousness. Fringe feelings are in themselves consciously experienced but have been demonstrated to reflect nonconscious context information and...
